HOSE-COUPLING.

Specification of Letters Patent.

Application filed December 16, 1909.

Patented Aug. 30, 1910.

Serial No. 533,409.

T 0 all whom it may concern:

Be it known that we, EDWARD H. WILsoN and SAMUEL J. GALLAGHER, citizens of the United States, residing at Coalinga, in the county of Fresno and State of California, have invented new and useful Improvements in Hose-Couplings, of which the following is a specification.

Our invention relates to a device for rapidly and efiiciently coupling hose and like conductors, and is especially adapted to making such couplings upon conductors of large diameter.

It consists in the combination of parts, and in details of construction which will be more fully explained by reference to the accompanying drawings, in which Figure l is a side elevation with parts connected. Fig. 2 is a plan view partly in section of the same. Fig. 3 is a side elevation with parts disconnected. Fig. 4: is a detail section on line AA, Fig. 1.

This invention is designed to provide for a rapid and eflicient coupling of hose and the like without the use of screw-threaded or equivalent couplers, which occupy a very considerable time.

As shown in the drawings, A and B are the two ends to which the respective parts of the hose to be coupled are connected. The part A has a socket, and the part B a corresponding tapered cone which fits therein, and when so fitted completes the joint. In order to draw these parts properly together we have shown a mechanism which is constructed as follows: 2 and 3 are bars, of which there is one of each upon opposite sides and about central of the line of the coupling. These bars are connected at 4 and 5 respectively wit-h the parts A and B, and at a point at each side of the actual joint. 6 represents a yoke-shaped lever, or there may be a pair of such levers, the outer ends of which may be connected so that they move in unison. The opposite ends of these levers are connected at 7 and 8 with the ends of the bars 2 and 3, and the distance between the fulcrum points 7 and 8 is such that when the levers are moved in one direction, the connections 2 and 3 will be pushed apart, and the distance between their fulcrum points 4 and 5 will be lengthened so that by disengaging one of the ends as at 4, the couplings may be readily separated. When they are to be joined the ends 4 are connected with the coupling member A, and

by then pulling the levers so as to shorten the distance between the points 4 and 5, the parts A and B of the coupling will be drawn together, and a perfect joint made.

The ends of the levers where they connect with the parts 7 and 8 may be curved or otherwise so constructed that when the coupling has been made, the fulcrum points 7 and 8 will have passed beyond each other, so that when the levers are moved to their fullest extent in closing the coupling, these fulcrums having moved beyond the center line, will form a sufficient lock to prevent the parts from being separated by any pressure from within. The links 2 and 3 on the opposite sides are preferably so connected that they will move in alinement in opening or closing.

Having thus described our invention, what we claim and desire to secure by Letters Patent is 1. The combination in a hose coupling, of members having their contiguous ends adapted to form a joint, bars having their outer ends connected respectively with the coupling members upon opposite sides, one of said bars having its outer end detachably connected to its coupling member, and levers to which the inner ends of the bars are fulcrumed, said fulcrum points being separated so that the movement of the levers causes the side bars to overlap and clamp the coupling members together.

2. The combination with hose coupling members having their contiguous ends adapted to form a joint, of side bars having their outer ends connected with the respective members upon opposite sides, the connection of the outer end of certain of said bars with their coupling member being a separable one, means by which the bars are caused to move in alinement, levers to which the inner contiguous ends of the bars are pivoted at separated points, said pivot forming fulcrums about which the levers are turnable, and whereby they act to shorten the united length of the bars and lock the coupling.

In testimony whereof we have hereunto set our hands in the presence of two subscribing witnesses.
